General introduction (Figure 1A-Figure 23)

Be packaged in lock body/shell 20' according to the padlock with double locking mechanism 10 of the embodiment of the present invention, lock body/Shell 20' has the forward part 30 shown in the rear section 20 shown in Figure 20 and Figure 21. By by Cipher mechanism 1000Dial-up dish 50 be set to and open password combination, and by the key associated with key mechanism 59 190, can beatOpen (release) this padlock. Control Cipher mechanism by dial-up dish 50. When all dial-up dishes 50 are turned to defaultWhen unlocking cipher combination (opening password combination), the opened gap 112 of clutch 110 is aimed at the extension of main shaft 90Projection 91, when this allows to see from front, integral clutch 110 (all clutches 110) with respect to shell 20 ' leftMobile (as shown in Figure 1A). Along with user upwards pulls latch hook 40, lower inclined plane 122 quilts of clutch extremity piece 120The lower inclined plane 131 of bar 130 promotes. So the surface 125 of clutch extremity piece 120 contacts the wall 115 of clutch 110.Along with clutch extremity piece 120 is promoted left by bar 130, integral clutch 110 also can be moved to the left, because allDial-up dish is in opening password combination (code of unblanking). So bar 130 can upwards move apart shell 20', because lockHook 40 is assembled in bar 130, and latch hook 40 will move up together with bar, the short leg 41 of latch hook 40 will discharge andLeave the lockhole 21 of lock body 20.

Latch hook 40 is sandwiched in upper/lower positions: the long leg 42 of latch hook is placed in the groove 134 of bar 130. Long leg ends atHeel 45. Short-leg ends at toe 47. Bar 130 is riveted with bar cover 140. In an embodiment of padlock,The inside of bar 130, tilting section (groove) 43 and the latch hook contact member 150 (for example bolt 150) of latch hook 40Assembling. Bolt has the curved surface 151 of the tilting section 43 of contact latch hook 40. Bolt 150 is departed to unique side of latch hookMethod is with key mechanism 59 releases, below will explain in detail. At the top of bar 130, latch hook 40 is also assembled with by twoThe circle part that individual subloop part 70 and 80 forms. The subloop part 70 of circle part has groove 72 and refers to the extension of holding latch hook 40Portion 44. The subloop part 70 of circle part and 80 and the latch hook 40 that is placed on above them be riveted together, as shown in Figure 2.Thereby any movement of latch hook 40 will directly be passed to the subloop part 70 and 80 of the circle part assembling. Circle part hasFunction for control latch hook reset function.

After riveted joint bar 130, bar cover 140, latch hook 40 and bolt wherein, with Cipher mechanism 1000 control levers.Bolt is controlled by key mechanism 59 is independent. Zhe Liangge mechanism independently controls latch hook moving from latched position to unlocked positionMoving, Zhe Liangge mechanism is non-interference each other simultaneously.

Key mechanism 59 is controlled by steering gear 60. In the time that correct key 190 enters, steering gear 60 rotate andThe cam 160 of key mechanism also rotates in the same manner. Steering gear and cam move in the same manner, because steering gear60 two of having in the hole 162 that joins all the time cam 160 to extend projection 62. Along with cam 160 rotates, protrudingThe skewed slot 161 of wheel 160 moves, and baffle plate 170 is dragged left, contacts all the time cam 160 because baffle plate 170 hasThe stretching pin 171 of skewed slot 161. Stretching pin 171 is followed the path of the skewed slot 161 of cam 160 all the time. This meaningAlong with cam 160 rotates, skewed slot 161 drags the stretching pin 171 of baffle plate 170 left, thereby the gear of baffle plate 170Face 172 also moves on to the left side. Along with the block face 172 of baffle plate 170 is moved to the left, latch hook contact member (for example bolt150) can be moved to the left. So inspector can upwards pull latch hook 40, the then inclined plane 43 of latch hook 40Promote the curved surface 151 of bolt 150 left, and the wall 152 of bolt 150 can be moved to the left to discharge latch hook 40.It should be noted, during the whole key operated processing, bar 130 is not along any (with respect to shell) Vertical SquareTo movement. Latch hook 40 upwards moves apart shell 20 ', until the edge 135 of inclined plane 43 trip rods 130.

In another embodiment of the padlock as shown in Figure 24 and Figure 25, there is the latching portion of bifurcation region 151AThe flat 145 of 150A contact latch hook 40, for respect to bar and shell locking or discharge (release) latch hook.

The advantage of this key mechanism is to allow traveller in their mechanism that accesses to your password during travel, and allows U.S.'s fortuneThe official of defeated safety management office (TSA) is by using key mechanism to check luggage.

Locking mode (Figure 1A-Fig. 3 and Figure 10-Figure 23):

As shown in Figure 1A-Fig. 3 and Figure 10, latch hook 40 is assembled to bar 130, bar cover 140 and bolt 150, andThe dial-up dish 50 of Cipher mechanism is not for example, in opening password combination (, 2-2-2-2-2), but in lock code(for example, 4-2-2-2-2). At least one opened gap 112 that this means clutch 110 is not aimed at main shaft 90Extension projection 91. This means that clutch 110 can not be moved to the left. This also means no matter apply to latch hookGreat motive force upwards, bar 130 can not move up. This is because the lower inclined plane 131 of bar 130 clashes intoThe lower inclined plane 122 of clutch extremity piece 120. The surface 125 of clutch extremity piece 120 contacts the wall of integral clutch 110115 to be moved to the left; But, extend projection 91 because at least one opened gap 112 is not aimed at, so do not permitBeing permitted clutch extremity piece 120 promotes left; Therefore, the lower inclined plane 131 of bar 130 still contact clutch extremity piece 120 underInclined-plane 122, this has just stoped latch hook 40 move up and discharge.

Latch hook 40 is sandwiched in upper/lower positions: the long leg 42 of latch hook is placed in the groove 134 of bar 130. Bar 130 and barCover 140 riveted joints. In the inside of bar 130, inclined plane 43 and the bolt 150 of latch hook 40 are assembled. The curved surface of boltThe inclined plane 43 of 151 contact latch hooks 40. The unique method that departs from bolt 150 is with key mechanism release padlock, underLiterary composition will be explained in detail. At the top of bar 130, latch hook 40 is also assembled with subloop part 70 and 80. Subloop part 70 hasGroove 72 is to hold the extension finger 44 of latch hook 40. Subloop part 70 and 80 and latch hook 40 be riveted on this position. This meaningAny movement that taste latch hook 40 will directly be passed to such as the subloop part 70 and 80 assembling. Thereby circle part plays workWith mode be control latch hook reset function, below can described.

Fig. 3 shows main shaft 90 and has square block 94, and square block 94 is positioned in the groove 23 of shell 20',Any movement of this arrangement constraints main shaft 90 (main shaft with respect to shell cannot rotate, vertical and/or move horizontally).Spring 100 inserts between the square block 94 of main shaft 90 and the inner surface 116 of integral clutch 110. This spring100 promote clutch 110 all the time, and the wall 115 of integral clutch 110 contacts the surface of clutch extremity piece 120125, this makes lower inclined plane 131 and the ramp 132 of clutch extremity piece 120 engaging levers 130. Main shaft 90 has smoothEnd 92, smooth end 92 is placed on the inside in the hole 124 being formed in clutch extremity piece 120. Clutch extremity piece 120Have wing member 121, wing member 121 is placed on the inside of the wing member groove 22 of the rear section 20 of shell 20 '. This prevent fromClose device extremity piece 120 and rotate, and only allow clutch extremity piece to move horizontally (moving left and right) with respect to shell. In addition,First (leftmost side that Fig. 3 sees) clutch 110 has fault recess 113, and it prevents that any effractor from prizing easilyDeclutch 110 actual aperture gap 112 to open padlock 10.

At lock-out state, key 190 does not exist, and disk plate 180 still stretches out, and this can prevent cylinder 60Rotate. Because cam 160 does not rotate, the skewed slot 161 of cam 160 does not move, and the stretching pin of baffle plate 170171 can not move. Because baffle plate 170 does not move, block face 172 can not move, and the wall of bolt 150152 can not be moved to the left, and therefore the curved surface 151 of bolt 150 engages the inclined plane 43 of latch hook 40. Latch hook 40Be locked in securely the inside of the lockhole 21 of lock body rear section 20.

With Cipher mechanism release (Fig. 4-Fig. 5):

Cipher mechanism 1000 comprises dial-up dish 50 and clutch 110. Dial-up dish 50 has receiving clutch 110Extend the tooth 51 of fin-shaped portion 111. Integral clutch refers to all single clutchs 110. Tooth and fin-shaped portion are protected all the timeHold and be engaged with each other, unless Cipher mechanism is in reseting state. When dial-up dish 50 is aligned to while opening password combination, rightAnswer the opened gap 112 of clutch 110 to aim at the extension projection 91 of main shaft 90. Because do not have thing block entirety fromClose device 110, so user can upwards pull latch hook 40, and assemble because of latch hook 40 and bar 130, so barAlso be pulled upward. The curved surface 151 of latch hook inclined plane 43 draw bolts 150. And bolt 150 is placed on barIn 130 bolt receiving channel 137. Because latch hook, bar and bar cover are riveted together, pulling of latch hook is passed toBolt 150, and bolt is arranged in bolt receiving channel 137. This layout will pull the lower inclined plane that is passed to bar 130131 (seeing Figure 12).

Along with pull lever 130 upwards, the lower inclined plane 131 of bar 130 contacts the lower inclined plane 122 of clutch extremity piece 120.So clutch extremity piece 120 is moved to the left, and the surface 125 of clutch extremity piece 120 promotes clutch 110 leftWall 115, wall 115 contacts the top flat surface 114 of next clutch 110. Due to this series reaction,Integral clutch 110 is moved to the left lockset position of coupler, and this allows along with upwards pull latch hook (leaving) from shell 20And pull lever 130 upwards.

Clutch extremity piece 120 has the inclined-plane of two different angles, lower inclined plane 122 and ramp 123, lower inclined plane 122Be used for opening password combination, ramp 123 is for reseting state. The angle that lower inclined plane 122 has allows to promote leftIntegral clutch 110, but keep the extension fin-shaped portion 111 of clutch to engage the tooth 51 of dial-up dish 50. Therefore, existOpen in password combination, the extension fin-shaped portion 111 of clutch 110 is moved to the left; But extending fin-shaped portion 111 still engagesThe tooth 51 of dial-up dish 50. And opened gap engages the extension projection 91 of main shaft 90, this prevents integral clutch110 in rotary moving and restriction dial-up dishes 50 rotate. Such structural advantage is, because when close in openingWhen code combination state, do not allow user to rotate dial-up dish, this can be avoided the problem (meaning in the time that latch hook is pushed back to latched positionPassword combination is opened in outer change).

Under this state because bolt 150 and latch hook 40 and bar 130 and bar cover 140 assemble, bolt 150 toUpper movement. The curved surface 151 of bolt 150 still engages the inclined plane 43 of latch hook; Therefore, along with pull lever 130 upwardsWith latch hook 40, bolt 150 moves up in a similar manner.

Reset state (Fig. 6-Fig. 7):

When dial-up dish 50 is when opening password combination, the opened gap 112 of clutch 110 is aimed at main shaft 90Extension projection 91.

Because assemble with the groove 72 in subloop part 70 the extension finger of latch hook 40 44, so any mobile of latch hook willAct in a similar manner subloop part 70 and 80.

User can upwards pull latch hook 40 so that short leg 41 is discharged to shell 20'. So user can the inverse timePin rotation latch hook, the groove 33 of reseting that makes the extension projection 71 of subloop part 70 aim at lock body 20 (is shown in Figure 1A and Tu6). Utilize this setting, latch hook 40 can be pulled down to enter the state of reseting (Fig. 6).

Along with downward (continuously) promotes latch hook 40, the upper surface 136 of basal surface 73 contact levers 130 of circle part. WithCatch bar 130 downwards, the ramp 132 of bar 130 contacts the ramp 123 of clutch extremity piece 120. As aboveThat mentions about Cipher mechanism is such, along with an inclined-plane contacts another inclined-plane, and the surface of clutch extremity piece 120125 promote the wall 115 of clutch 110 left; Therefore, integral clutch is moved to the left. It is different from assembled state,Now, the ramp 123 of clutch extremity piece 120 and the ramp 132 of bar 130 further promote overall clutch leftDevice 110, this makes the extension fin-shaped portion 111 of clutch 110 depart from the tooth 51 of dial-up dish 50 completely. So userCan rotate the open password combination of dial-up dish 50 to new expectation. Meanwhile, the opened gap 112 of clutch 110Engage the extension projection 91 of main shaft 90 completely, this prevents any in rotary moving of clutch 110. And, when inWhile reseting state, the taper 133 of bar is pushed out main body 20 and comes out, as shown in Figure 6.
